There are few activities in life that utilizes the entire brain, and music is one of them.
With Functional Magnetic Resonance Imaging (FMRI), a research team recorded a group of individuals who were listening to music. They found that listening to music recruits the auditory areas, and employs large-scale neural networks in the brain. In fact, they believe music can activate emotional, motor, and creative areas of the brain.(source)
Why does sound travel farther on a cold day?
Cold air slows down the speed of sound, but it also makes sound travel farther.
Cold air forms a dense, heavy mass that sits down at ground level.
Air a little above is actually warmer – a phenomenon called temperature inversion.
Sound waves bend from air that is less dense toward air that is colder and more dense.
Sound waves emanating from a person talking on the ground are refocused toward the ground.
The sound follows a curved path, and therefore travels farther.
In February 1947, the temperature in Snag, Yukon reached –62.8 degrees Celcius.
